CPU Overclock - Have I reached limit/wall?

Hello, have an i7 4930K with an ASUS X79-Deluxe. Clocked 4,5GHz @ 1.39V for daily use. Can't get it stable at higher than 4531MHz (anything above this frequency results in bluescreens, even with 1.45V). Is it impossible for me to get 4,6GHz for example? Below are some pictures of Cinebench scores with different clocks & BCLK, as well as BIOS config pictures. Are there any settings I have overlooked that may help me get 4,6 stable? Let me know if you want additional pictures of bios settings or info.

It really depends on your luck with the so called silicon lottery... 

 

Some K Cpus overclock until the clock breaks and a temporal rift forms... others might not get as high... it really depends on luck. 

 

So it really is a big chance that your CPU won't clock higher no matter what.

Main System:

Anghammarad : Asrock Taichi x570, AMD Ryzen 7 5800X @4900 MHz. 32 GB DDR4 3600, some NVME SSDs, Gainward Phoenix RTX 3070TI

 

System 2 "Igluna" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

System 3 "Inskah" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

 

On the Road: Acer Aspire 5 Model A515-51G-54FD, Intel Core i5 7200U, 8 GB DDR4 Ram, 120 GB SSD, 1 TB SSD, Intel CPU GFX and Nvidia MX 150, Full HD IPS display

 

Media System "Vio": Aorus Elite AX V2, Ryzen 7 5700X, 64 GB Ram DDR4 3200 Mushkin, 1 275 GB Crucial MX SSD, 1 tb Crucial MX500 SSD. IBM 5015 Megaraid, 4 Seagate Ironwolf 4TB HDD in raid 5, 4 WD RED 4 tb in another Raid 5, Gainward Phoenix GTX 1060

 

(Abit Fatal1ty FP9 IN SLI, C2Duo E8400, 6 GB Ram DDR2 800, far too less diskspace, Gainward Phantom 560 GTX broken need fixing)

 

Nostalgia: Amiga 1200, Tower Build, CPU/FPU/MMU 68EC020, 68030, 68882 @50 Mhz, 10 MByte ram (2 MB Chip, 8 MB Fast), Fast SCSI II, 2 CDRoms, 2 1 GB SCSI II IBM Harddrives, 512 MB Quantum Lightning HDD, self soldered Sync changer to attach VGA displays, WLAN

if you want to push further, you will have to disable most of the cpu dynamic features, like C states and features like virtualization and hyperthreading, and go fixed voltage. Having the CPU throttling the vcore and frequency is just another point of failure.

But for 24/7 i believe 4.5 is respectable.

C states is already disabled, voltage is fixed, and I need HT enabled.
